E55 K LPG conversion ?

[smillion]

Does anyone have any practical experience about whether this can be done effectively? I have tried to search the forum but LPG is too short a term for the search facility. Apologies if this is therefore an old chestnut

If you think it's of any help I have a mate with a supercharged Jaguar XJR 4.0 who has a LPG conversion. Would you like me to ask where he had it done and/or what the issues are? He's based in north London so I guess nearby.

Last time I spoke to him about it he says he has to start the engine with petrol, wait for the engine to warm up before switching to LPG.

HTH

I have a 1996 V8 Disco, with an after market LPG kit. It was done in about 2001 and I bought the car in 2007 with 92,000 miles on it. It has now covered 123,000 miles.

The LPG kit has been faultless (the whole car is very good). It has been the best motor I've ever had!

Here's a response from my mate

It was Neal Mugglestone who runs this place:

I think he'll do other non Jaguar cars, but otherwise, the other place I looked at that has a similar reputation is called Go LPG

http://www.go-lpg.co.uk/

There are plenty of others and an industry association so depending on location these may not suit...

The only negative comment I make is that for really powerful cars (over 300 bhp) pretty much all the LPG systems can struggle to cope, so despite what the websites say, you'll get some occasions when the power isn't there on LPG where it would be on petrol - so a sort of lag, happens when you get sudden power demands... other than that all is fine from my point of view. Its worth trying to speak to someone else with an LPG conversion of that type/model of car to see how much of a problem this is though, I certainly did and found it useful.

A 460 BHP supercharged E55 will never run properly on LPG

An old V8 Land Rover is a very different engine to the E55 , just about the only similarity is that it has 8 cylinders ...

i have a few friends who have gone down the lpg route. one had his 98 E39 540i auto done. that worked quite well. Another had his subaru impreza turbo done and after 6/12 - his engine went. I would not dream of having an e55 converted.

I would've said that W211 with superb performance and a nod to economy = E320 CDI.

An E55 with LPG sounds like a bad idea, that's even before the considerations of cost of installation, where the tank would go (ruins the boot etc), depreciation, insurance complications etc etc.

I really wouldn't LPG a forced induction high performance car.

A friend of mine bought a brand new C class W203, had it LPG converted, engine seized at 20000miles.

The correct initials are AMG - not LPG

I considered LPG for my Omega 3.0 years ago and after much research and number crunching decided against it.

Sure, you pay less per gallon for LPG but LPG burns faster than petrol so the benefits are not as great as you would think and to get back the install costs you would have to cover a significant mileage.

Even a speciallist LPG outfit could have problems with or after the install (especially if yours is the first they have converted) so I suggest you stick to the original spec.

I have yet to hear if anyone that has done an E55K. There are some testimononials from W210 owners on the web but not W211.

Here were my expectations:

1. Cost £2,500, recovered in 12-14 months at my mileage.
2. Reduced power (5-10%) when in use, and at higher revs, but you can turn it off. remember this car has over 475bhp, and on my daily commute the best I get of that is the sound

What has become clear however is that there are a number of horror stories that seems to be associated with an LPG conversion - everyone seems to know someone who's had problems with their engine i.e. poor running; engine management or just complete failure. And it is this overriding question mark and uncertaintly that is making me (and no doubt many before me) shy away from the RISK.

The problem I have is that its all anecdotal - I just wish, as the OP states, someone had practical experience of the E55K.

Thanks to wemorgan for the feedback regarding his Jaguar owning friend.

i had my 500SEC sone recently and havent had any problems with it so far, granted its a much older system with fewer components but you will definitly feel a warm smug glow as you fill up at 45 pence per litre, plus theres hardly ever a que to fill up at the LPG pump. If you do it get it done dont cheap out and definitly get the biggest tank you can fit in. If i could do it again i would have put got my petrol tank replaced with a smaller one to make space for a much bigger LPG tank.
